SK ATX-POT
The category 3D variable frequency drive can be equipped with an ATEX-compliant 10 kΩ
potentiometer (SK ATX-POT) which can be used for setpoint (e.g. speed) adjustment on the device.
The potentiometer is used with an M20-M25 extension in one of the M25 cable screw connections.
The selected setpoint can be adjusted with a screwdriver. Due to the detachable cap, this component
complies with ATEX requirements. Permanent operation may only be carried out with the cap closed.
